Most people treat stress as something to calm down from. TJ Power's endorphin model inverts that: for 300,000 years the only two stressors were hunger and danger, and both were resolved by hard physical exertion, which released endorphins to strip fear and stress out of the brain so you could act. Modern stress arrives without the movement, so the two signature symptoms of low endorphins — a tight, fast-paced worried mind, and anger or frustration — go unresolved. The law of endorphins is to physically push your body every day. Movement comes first, relaxation after. Five actions supply the exertion: exercise, heat, singing, laughter and stretching.

How to run it
- 1
Move first, chill second
When stress or irritability arrives, read it as the body asking for movement rather than for wine and Netflix. Reverse the usual order: move first, then relax. Numbing stress with a dopamine spike only exacerbates the problem long term.
Pro tip Frustration is the clearest tell — if you want to punch a wall, your body is literally asking to exert itself.

Train hard on high-motivation days
On days when dopamine and motivation are high, do a hard 60-minute workout. Maximum endorphin release happens in the moments where you are physically struggling the most — the final reps you can't be bothered to do are the ones that count.
- 3
Use walk-run on low-motivation days
On days you refuse to exercise, go for a 20-minute walk, ideally headphone-free, and pick three moments — a small hill works — where you sprint as if a bear is behind you. Three short bursts activate the chemical without needing a workout.
Pro tip Nobody is watching; people are focused on their own experience and will not even notice you sprint past.
- 4
Use heat when exercise isn't possible
A sauna or bath triggers a heat stress response: the body treats the heat like impending physical danger and prepares accordingly, releasing endorphins. Allow about 15 minutes in the hot environment.
Watch out A hot shower is worse than a bath or sauna simply because few people stay in one for the 15 minutes required.

Sing out loud for five minutes a day
Singing — properly, not humming — puts the body through physical work and has a euphoric effect. Hunter-gatherers chanted and sang; religious practice kept humans singing until recently. Sing in the car, on a walk, in your bedroom; quality is irrelevant.
Pro tip The harder you actually go for it, the more you enjoy it, because the effort is what releases the chemical.

Engineer laughter environments
Rate your current laughter from 1 to 10 — TJ's training data averages 5.7. Then ask what environment would actually make you laugh today, and put yourself in it: see people in person, or FaceTime the friend most likely to make you laugh and ask them to try.
Watch out Watching funny clips only counts if you genuinely laugh out loud — and it risks burning dopamine at the same time.

Do ups, downs and twists
If yoga is unbearable, use TJ's minimal stretch on waking and before sleep: reach up as tall as you can, reach down to the floor, then twist your spine. It counters seated posture by opening shoulders, mobilising the spine and lengthening hamstrings.
Pro tip Slot it into dead moments — while cooking, waiting, or getting out of bed.
In the wild
TJ contrasts modern life with the Hadza, a tribe still functioning in Africa, who average around nine hours of movement per day — a reasonable proxy for what humans did for 300,000 years. Against that, a modern person is lucky to get 30 to 60 minutes, while facing constant non-physical stressors like bank statements and arguments that the body still expects to resolve through exertion.
→ The mismatch explains the two modern low-endorphin symptoms TJ names: a tight, fast-paced worried mind and persistent anger or frustration.
Ali Abdaal describes getting more jacked with a personal trainer but not enjoying weights, while loving squash, badminton, tennis and padel. Asked whether resistance training is essential, TJ says if the choice were only gym or only sport he would pick sport — for the competitive element, the human connection and the visible progress. He adds that he switched to CrossFit-style training himself because the varied movements and competitive element give a clearer mountain to climb than adding two kilos to a lift.
→ His desire to actually turn up rose; where resistance training is the path, he prescribes hard targets like benching 80kg for five reps by June 1st.
Common mistakes
Unwinding from stress with wine and Netflix
It temporarily removes the pain by forcing a high-dopamine state where no stress registers, but it skips the exertion the body was asking for and makes the underlying stress worse over time.
Coasting through the easy reps
Endorphin release peaks in the moments of greatest physical struggle. A comfortable workout that stops before the hard final reps leaves most of the de-stressing effect on the table.
Forcing yourself into yoga you hate
Stretching releases endorphins, but an hour of yoga you dread will not survive contact with a busy week. A 60-second ups-downs-and-twists routine done twice daily beats an abandoned class.
